Long story short(er): -Wife at work can't find phone. "Is it at home?" -Call phone. No answer. -Fire up 'Find My iPhone'. Look like it's in her car in the lot, Humbolt Park Chicago. -"I searched my car, but oh well I'll get it later." -She calls again about 1/2 hour later, still can't find it after looking again. -I look again at FMI and it has moved a few miles! Now I'm upset she lost her phone out of her oh-so-loose mesh backpack pocket I'm always warning her about and somebody has obviously picked it up. -I pack up our baby and head out in my car to track it down wondering what am I going to do if I find some young thugs in a sketchy neighborhood... -After getting within about 12 blocks heading north through Cicero and Belmont, the signal goes dead. "Great" they've turned it off. Time to give up and get a doughnut to soothe my anger/nerves. I lock the iPhone remotely in case they turn it on or reactivate location services. Probably should have done that immediately. -On a hunch I look again after my doughnut break. Haha! It's back and not moving. I head to the location near Cicero and Irving Park. Nothing is around but a small businesses and a small apartment building. Baby's getting hungry. Phone not moving. What to do? -The signal seems very accurate so I make my best guess and go into the small business. There are three old guys waiting and a receptionist. It's very noisy. I hit the 'Send Message/Sound' button. I think I hear something, but it's hard to tell. I walk around. People look at me oddly. I swear it's coming from one of the old guy's backpacks but... I say, "Is that your phone ringing?" and I get a shrug. Still not sure if the sounds I'm hearing are the iPhone or just some other phone. Sound stops after about one full minute. I reactivate "Send message/Sound" and sure enough the sound come back almost immediately, definitely from the middle guy's backpack. Now, more firmly I say, "I think you have my phone in your backpack. Do you have a pink iPhone?" Now he opens up the pack and gets out the phone and hands it to me. I say thank you, ask where he got it. He looks to the receptionist and she asks him again in Polish. He says, "Humbolt Park". I leave, just happy to have it, not wanting to linger for whatever reason. -Now I suppose he might have returned it on his own. Maybe he was waiting to show someone more English proficient and have them call/return it. I'd like to think so but... either way, I'm glad that we had Find My iPhone activated on the phone; and that he was about 65 years old and not 20, large and tough.
